During it's 6 year lifespan, the NaCl client contributed 48 million
Folding@home work units towards the study of human diseases. This
represents a contribution of roughly 1.3 million CPU days.

Our decision to retire the NaCl client was due to a combination of Google deprecating NaCl and infrastructure upgrades at
Folding@home which would have required extra effort to continue to
support the NaCl folding client.
